in some minor trait which is not immediately discernable to the
casual observer such as seasonal color variations, bloom traits, ploidy, etc. So, as Warren mentions, hostaphiles may differ as to the
plants listed but then, their opinions are based on visual observations and interpretations.

article. Following an algebra rule I learned in the last century, if
A=B and B=C, then A=C so all the hostas on both lists should be
List #1 - H.
